A scientist crosses a rabbit with short fur and a rabbit with long fur. which of these outcomes would show that the trait for fu
maks197457 [2]

Answer:

d. all of the offspring have medium length fur.

Explanation:

Incomplete dominance is a phenomenon in which offspring produce a trait that is intermediate between the two forms of a certain trait.

For example: In four o clock plant, some plants produce red flowers while some plants produce white flowers. When plants with red flowers are crossed with plants with white flowers, all the offspring have pink flowers.

Why is that so?

This is because no allele is completely dominant over the other and therefore both contribute their individual effect by producing intermediate phenotype.

Example in question:

Cross between a rabbit with short fur (SS) and a rabbit with long fur (LL)

P1:                                SS        x        LL

Gametes:                     S     and  L

Offspring                        SL :SL

SL: Medium length fur

Therefore this is a case of incomplete dominance.

Hope it help!

42. Variation which exhibits a wide range from one
kirill115 [55]

Answer:

C. continuous variation.

Explanation:

Variation within organisms refers to how different they are from another. In biology, variation can either be a continuous one or discontinuous.

A continuous variation is a type of variation in which there is a wide range of values from one phenotype/extreme to the other. In other words, there are a lot of values in between the extremes. For example, the human height can range from different degree of shortness to a different degree of tallness. Hence, human height is an example of a trait that exhibit continuous variation.

Therefore, a variation which exhibits a wide range from one extreme to the other is CONTINUOS VARIATION.
